Abstract
A formulation for finite element plane strain limit analysis of rigidly perfectly plastic solids governed by von Mises' plasticity condition is presented. The approach is based on the kinematic theorem of limit analysis formulated as a minimum problem for a convex and non-smooth dissipation functional. In particular, the mixed 4-node rectangular element presented by Capsoni and Corradi (1997) is reformulated to keep into account isoparametric mapping while ensuring a locking free behaviour and low distortion sensitivity.
